JACQUARD-GARD-PUNCHING MACHINE.

Application filed July 16, 1913.

To all whom it may concern:

Be it known that I, CHARLES H. LANDEN- BERGER, a citizen of the UnitedStates, residing in Philadelphia, Pennsylvania, have invented certainImprovements in J acquard- Card-Punching Machines, of which thefollowing'is a specification.

The object of my invention is to provide a machine for punching cardsfor a jacquard machine intended to be used in a loom for weaving fabricsof the oriental rug type, in which short pieces of yarn are knotted ontothe warp threads of the fabric so that the upstanding ends of the knotsconstitute the pile of the fabric. Usually such fabrics are produced byknotting the tufts onto the warp threads by hand and they areconsequently very expensive. For this reason numerous attempts have beenmade to produce a power loom on which such fabrics can be woven. Oneinstance of such power loom is to be found in my U. S. Patent No.706,072, dated August 5, 1902. In such looms mechanical devices areemployed for engaging the pieces of yarn which are to form the tufts andknotting the same around corresponding threads of the warp and in orderto cover the relatively wide range of colors employed in the patterns ofsuch fabrics there must be employed, in connection with each of theknotting devices of the loom, a yarn supplying device (hereinafter forconvenience denominated a color box) supplied with yarns of as manycolors as there are in the color scheme of the pattern, and each ofthese color boxes must be adjusted so as to pre-.

sent any desired one of the yarns carried thereby, to the correspondingknot forming devices of the loom. Although I have described herein meansfor mounting such color boxes and operating them by means of an ordinaryjacquard machine so as to effect the presentation of yarns of the propercolors to the knot forming devices at the proper times, such means arenot intended to be claimed herein but will form the subject of aseparate application. In connection with the jacquard machine speciallypunched cards are required and my present invention relates to themachine for punching such cards.

In the accompanying drawings-Figure 1 is a plan or top view of themachine; Fig. 2 is a longitudinal section of the same on Specificationof Letters Patent.

In order that the purpose of my improved card punching machine may bebetter understood it will probably be best to preface the description ofthe construction and operation of said machine with a description of theoperation of so much of the loom as will convey an understanding of thearrangement of the color boxes in respect to the warp threads of theloom and of the means for adjusting said color boxes so as to presentany desired one of the colored yarns carried therebv for the action ofthe corresponding knot forming device.

The warp threads of the loom are divided into sets, such for instance asillustrated at w in Figs. 8 to 11, and for each set is provided aseparate color box y. If, for instance, there are in a single lineextending across the fabric 960.colored knots or tufts and the warp iscomposed of 960 pairs of threads, one pair for each knot, and isfurthermore divided into 2&0 sets at each comprising four pairs of warpthreads w, w 10 and w, there will be 240 different color boxes g eachsupplying the knot forming yarns to its own set of warp threads, andsupplying the yarn successively to each pair of warp threads of the set.In forming a complete line of knots across the fabric, therefore, foursuccessive operations ofthe loom will be required. During the firstoperation the yarns supplied by each of the- 240 different color boxeswill be applied to the first pair of warp threads w of the correspondingset as in Fig. 8, not, however, by direct delivery of the yarn from thecolor box to the warps but by intervening delivery mechanism representedconventionally in Figs. 8 to 11 by a line 2 and shifting from one pairof warp threads of each set to the next on each operation of the loom.During the next operation the yarns will be applied to the second pairof warp threads in of each set, as in Fig. 9; during the third operationthe yarns will be applied to the third pair of warp threads 41: of eachset, as in Fig. 10, and during the fourth operation the yarns will beapplied to the last pair of warp threads 10 of each set, as in Fig. 11..A knot having now been formed upon each pair of warp threads from sideto side of the fabric the warp threads will be shedded for the receptionof the binding weft thread or threads and the formation of a succeedingrow of knots will then be proceeded with in like manner.

The different colored yarns are disposed in a row in each color box 1and each color box is adjustable longitudinally so that any desired yarnof the latter may be presented at a fixed delivery point so as to begrasped by a pair of nippers whereby a sufficient length of yarn iswithdrawn from the color box to form the desired knot, is. then cut offand is conveyed by the nippers to the knot forming devices. Means foreffecting such longitudinal adjustment of the color boxes so as topresent any one of the row of. differently colored yarns carried therebyto the nippers is represented in Fig. 7 and may be briefly described asfollows: The color box 2 is mounted at the lower end of a parallelmotion device comprising a lever arm a and a link (Z pivotally mountedupon tranverse rods 0 and (Z. the lever also having an arm 0 pivotallyconnected at its upper end to a bar 6 to which reciprocating movementcan be imparted at the proper intervals, positive movement of the bar inone direction being due to contact of a finger e on said bar with aswinging bar f and yielding movement of the bar in the oppositedirection being effected by means of a coiled spring 7 connected to thefinger 6. Between abracket 9 depending from any suitable fixed portionof the loom and a shoulder g on the bar 6 are interposed a series ofwedges h, B, 7& and k these wedges having different angles of inclination, for instance the wedge it may represent one unit of inclination;the wedge h two units; the wedge 71 four units, and the wedge it eightunits. This combination of wedges provides for sixteen differentadjustments of the color box and hence for the employement of. sixteendifferent colored yarns in said color box and the presentation of anydesired one of said yarns to the knot forming devices of the loom.

When the bar 6 is-moved to one extreme of its reciprocation, as in Fig.7 the color box 3 is also adjusted to one extreme of its movement andthe colored yarn 16 will, if the color box is retained in that position,be presented to the nippers for supplying the knot forming devices.Between the stems of the wedges h, 7L2, h and it are interposed studs 2'free to slide in a slot z" in the bar 6 and each of a diameter equal tothe distance between the stem of one wedge and that of the next whensaid wedges are in contact, or between the wedges themselves when theyare separated as in Fig. 7 The distance between the bracket g and theshoulder g of the bar 6 when said bar is fully projected is such thatwhen each of the wedges is lifted, so as to occupy said space, thelatter will be filled and no retraction of the bar 6 by the spring fwill be permitted on the retraction of the swinging bar 7, consequentlythe combined action of the four wedges, representing fifteen units, orthe difference between the location of yarn 1 and yarn 16 in the colorbox, will result in the presentation of yarn 16 at the delivery point.The raising of a wedge 01' wedges representing any less number of unitswill result in the presentation at the delivery point of a yarn so manyunits removed from yarn 1, the latter being presented when none of thewedges are raised.

Each of the wedges is connected to a depending harness cord m of thejacquard machine and the yarn presented by each color box on eachoperation of the loom will therefore depend upon the number and locationor grouping of the harness cords corresponding to said color box whichare raised at such operation of the loom.

Each of the harness cords m is controlled by aneedle of the jacquardmachine, hence each color box must be represented on each card of saidmachine by four spaces. If all of these spaces are punched all four ofthe needles corresponding thereto will remain in the retracted positionand all four of the harness cords represented by said needles will beraised. If the space corresponding to any one of the needles is blank,however, that needle will be projected by the card and harness cordcorresponding to it will not be raised.

In Fig. 6 is shown a diagram of the sixteen colors of the color box,running from 1 to 16, and of the manner in which a card must be punchedto call either of these colors. In order to call color 1, whichnecessitates the remaining down of all four of the wedges, all of thespaces on the card are blank, as shown in group a card S; in

order to call color 2, a space on the card corresponding to wedge h ispunched, as shown in group n, card S in order to call color 3, a spaceon the card corresponding to wedge k is punched, as shown in group a,card S to call color 4, spaces on the card corresponding to wedges h and72. are punched, as shown in group n, card S and in like mannerthroughout all of the other colors until finally to call color 16, allfour spaces are punched as shown in group a, card S, so that all of thewedges will be raised.

Each card provides for a transverse row of sixteen spaces and, as eachcolor box requires four spaces, each transverse row of spaces on thecard corresponds to four color boxes and in a loom having 240 differentcolor boxes there would have to be sixty of said transverse rows in thelength of the card, the first row representing the first four colorboxes, the second row the next four, and so on. As it takes foursuccessive operations of the loom to produce one complete line of knotsacross the fabric the cards are likewise in sets of four, one for eachoperation of the loom, thus considering only the first row of each ofthe cards S, S, S and S card S represents the adjustment of the firstfour color boxes, in order to supply yarn to the first pairof warpthreads of each of the four sets :20, as in Fig. 8, card S representsthe adjustment of said first four color boxes to supply yarn to thesecond pair of warp threads of each set, as.

in Fig. 9, card S governs the feeding of yarn to the third pair, as inFig. 10, and card S to the fourth pair, asiin Fig. 11.

Of course, in practice, each group of spaces on each card will bepunched to accord with the color which it is to call. The cards shown inFig. 6 are punched to call the sixteen colors in regular sequence, cardS. calling color 1, box 1; color 5, box 2;

color 9, box 3, and color 13, box 4; card S calling color 2, box 1;color 6, box 2; color 10, box 3, and color 14, box 4; card S callingcolor 3, box 1; color 7, box 2; color 11, box 3, and color 15, box 4;and card S calling color 4, box 1; color 8, box 2; color 12, box 3, andcolor 16, box '4.

The machine which constitutes the subject of my present invention hasbeen devised with the view of punching at one and the same time acomplete row on each of the four cards of a set. The construction andoperation of the machine will be understood upon reference to Figs. 1 to5 inclusive of the drawings. I

The stationary bed of the machine is composed of upper and lower members17 and 17 between which are formed four slots 18 for the reception ofthe four cards of the set, said top and bottom members also havingformed in them registering openings 19 each intended for the receptionand guidance of a punch 20-of which there are four sets of sixteen each,one set for each card. These punches are carried by a vertically movablepunching head 21, as shown in Fig. 3. On the underside of the bottommember 17 of the fixed frame are formed guideways 22 for the receptionof a laterally movable carriage 23 which has step by step forwardmovements imparted to it in any appropriate manner. In the presentinstance I have adopted for this purpose mechanism similar to thatwhichcontrols the operation of the carriage of an ordinary type writingmachine butthis is simply selected as a convenient "means for thepurpose and is not essential.

Mounted in bearings on the carriage 23 are four rock shafts 24, 25, 26and 27, and secured to each end of eachof these rock shafts by means ofdepending arms 28 is a blade 24, 25, 26, or 27 which can therefore swingwithin a limited range from front to rear,'coiled-springs 29 at each endof the'carriage 23 serving to actupon the arms 28 so as to tend toconstantlyimaintain the blades in the retracted position shown-in Fig.3. Guided'in suitable bearings 30 mounted upon the upper member 17 ofthe fixed frame of the machine are four sets 8', s 8 and s of jackswhich, for identification I will hereinafter refer to as punch jacks,one set for each of the four cards to be punched, each of these setscomprising sixteen jacks and each set being divided into four groups,each comprising four jacks 31, 31 31 and 31 Each of the punch jacks ofeach group has on its under side a depending lug 32 and each of theblades 24, 25 26 and 27 has on its upper face four upstanding lugs 33one for each of the sets 8, s 8 and is of punch jacks. The lugs 33 ofthe blade 27 act upon the punch jacks 31 of each group, those of theblade 26 upon the jacks 31*, those of the blade 25 upon the punch jacks31, and those of the blade 24 upon the punch jacks 31 The lugs 33,however, are so disposed as to act upon the punch jacks of only onegroup at a time, for instance, as shown in Fig.1, the lugs 33aredisposed so as to act upon the punch jacks of the first group o'f sets, the lugs corresponding to set 8 being one step of the carriage 23behind the'punch jacks of the first group of set 8 and the lugscorresponding to sets .9 and s being,'respectively, two 7 steps andthree steps behind the punch jacks of the first groups of those sets.The

swinging blades will therefore operate upon the punch jacks of the firstgroup of each set in succession, then upon those of the second group,then upon those of the third group, and then upon those of the fourthgroup. 7

Each of the punch jacks of each of the sets .9, s 8 and .9 acts upon thehead of a bolt 34: guided in thepunch carrying head 21 and normallyretained in the retracted position shown in Figs. 3 and 3 by means of aspring 35 surrounding the contracted stem of said bolt and acting uponthe head of the same. When thus retracted the bolt 34: offers noresistance to the rise of its corresponding punch 20, when, on thedescent of the head 21, the lower end of said punch contacts with acard. hen either of the punch jacks 31 31 31 or 31 is projected,however, it will project its corresponding bolt 3% and the latter willbe held in the projected position by means of a springactuated trigger36 which drops behind the rear end of the bolt, as shown in Fig. 3,

' each projected bolt serving to look its corresponding punch so that onthe descent of the head 21 each one of the punches so locked will forman opening in the card upon which it acts. As the punching head 21approaches the limit of its downward movement the tails of the-triggers36 strike and deflect, as shown in Fig.3, a bar 37, suspended from apivotally mounted rod 38 so that it is capable of swinging rearwardlyfrom the position shown in Figs. 3 and 3 against the action of a spring39 which tends normally to hold it in the position shown in thelatter'figures, the-suspension armsof the bar when 111 suchpositioncontacting with a lug 10 on the supporting bracket as thereshown. On the rise of the punching head 21 the tails of the triggers 36strike the under side of the bar 37 and are tripped thereby, as shown inFig. 3 so as to release the bolts 34: and permit them to be retracted byreason of the action of the springs 35 on the heads of said bolts.

In Fig. 6 I have indicated by the letters 9, S S and S. the four cardscorresponding to the four sets 8, 8 s and s of punch jacks and by theletters n, 02 n and n the four groups of spaces in the transverse row ofeach card corresponding With the four groups of punch jacks in thecorresponding set 8, 8 s or s.

Mounted so as to swing upon a. shaft or spindle 1-1 carried by one ofthe bearings 30 are a series of bell crank levers 42, here inafterreferred to as key levers, one arm of each of these. levers engaging aslot in the spring-supported stem 43 of a key if and the other arm ofeach of said levers being slotted for the reception of a pin 45 on akey-jack 4), said key-jacks being guided in the front and rear bearings30 so as to slide therein. There is one key for each of the coloredyarns employed in the color boxes, and, in the drawing, the differentkeys are numbered from 1 to 16 to correspond with the different yarnswhich they represent, and the corresponding key-jacks 1), shown in 5,are likewise numbered.

Each of the key jacks differs from each of the others, thus, as shown inFig. 5, the key jack 1 has, with the exception hereinafter noted, astraight upper surface but each of the other key jacks has one or moreupwardly projecting lugs 46. The key ack 2 has a single lug adapted toact upon the swinging blade 24*, the key jack 3 has a single lug adaptedto act upon the swinging blade 25, the key jack at has two lugs oneadapted to act upon the blade 24 and the other upon the blade 25 the keyjack 5 has a single lug adapted to act upon the blade 26 the key jack 6has lugs adapted to act upon blades 24 and 26, the key jack 7 has lugsadapted to act upon the blades 25 and 26 the key jack 8 has lugs adaptedto act upon the bars 24*, 25 and26 the key jack 9 has a single lugadapted to actrupon the blade 27, the key jack 10 has lugs adapted toact upon blades 24 and 27 the key jack 11 has lugs adapted to act uponthe blades 25 and 27, the key jack 12 has lugs adapted to act upon theblades 2?, 25 and 27 the key jack 13 has lugs adapted to act upon theblades 26 and 27, the key jack 14; has lugs adapted to act upon theblades 24?, 26 and 27*, the key jack has lugs adapted to act upon theblades 25 26 and 27 and the key ack 16 has lugs adapted to. act upon theblades 2%, 25226 and 27 The number of blades which will be caused toswing on each operation of the machine will therefore depend upon whichof the keys is depressed. If the key corresponding to the key jack 16 isdepressed all four of the blades will. be actuated and all four of thepunch jacks 31, 31". 31", and 31 will be projected so as to lock inposition all four of the punches corresponding to said group,consequently on the descent of the punching head 21 all of the punchesof said group will be depressed and four punchings will be formed in thecard as represented in connection with color 16 in Fig.6. If, on theother hand, the key which operates key jack l'is depressed none of theblades will be actuated and neither of the group of punch jacks 31 31 31and 31. will be projected, consequently the locking bolts 34ccorresponding to said group will remain in their retracted positions andthe punches 20corresponding thereto will, on the descent of thepunchinghead 21 be free to rise and the group of spaces on the card willbe left blank, as indicated in connection with color 1 in Fig. 6.Depression of any of the other keys will cause the formation of punchholes in one, two or three of the spaces of a group on the carddepending upon the actuation of one, two or three of the swinging bladesand the projection of one, two or three of the punch jacks of a group.

Each of the key jacks has on its upper side a proj ectirfg lug 47 whichupon the projection of the key jack, acts to swing forwardly a blade 48carried by a rock shaft 49 mounted in bearings on the fixed frame of themachine and having a depending arm 50 which carries at its lower end anadjustable set screw 51 adapted to act upon an arm 52 projecting from arock shaft 53, likewise mounted in bearings on the fixed frame andhaving an arm 54 carrying escapement pawls 55 and 55 which cooperatewith. a toothed escapement wheel 56 secured to a shaft 57 the latterbeing connected by suitable interposed gears to a shaft 58, having aspur wheel 59 which engages with a rack 60 on the under side of thecarriage 23, as shown in Figs. 2 and 3. The swinging blade 48 isnormally held in its retracted position by means of .a spring 61 locatednear one end of the rock shaft 49, movement of the blade in thisdirection being limited by contact of an adjustable set screw 62 on thearm 50 with a stop on the fixed frame of the machine, as shown in Fig.3, and movement of the rock shaft 53 and its arm 52 in the direction ofthe arrow Fig. 3 being caused by a coil spring 63. This construction,being substantially that of the carriage mechanism of an ordinarytypewriting machine, forms no part of my invention and any equivalentdevice may be substituted therefor. On each of the punch jacks is adepending lug 65 which, on the retraction of the blade 48, is struckthereby so as to restore the projected punch jacks to their retractedpositions.

Operation of any one of the keys t, will cause movement of theescapement tothe extent of one tooth of the wheel 56 and the lateralmovement of the carriage 23 to the extent of one step. When saidcarriage is at one extreme of its movement the blades 24, 25, 26 and 27a operate in connection with the punch-jacks of the first group of thefirst set sbut all of the remaining punchjacks both of this group and ofthe other three groups will be free from the influence of said swingingblades. After the first advance step of the carriage 23 the punchjacksof the set s will be freed from the action of the blades andthe latterwill co6perate with the first group of punch-jacks of set 8 on thesecond advance step of the carriage the punch-jacks of the first groupof set 8 will be acted upon, and upon the third advance step of thecarriage the punch-jacks of the first group of set 8* will be actedupon. The next four steps in the movement of the carriage 23 will bringinto action the second group of punch-jacks of sets .9, 8 s and s insuccession, the next four steps will bring intoac tion the third groupof punch-jacks of each of said sets in succession, and the next foursteps will'bring into action the fourth group of punch-jacks of each ofthe successive sets. The punch locking bolts for each group of puncheswill by this time, have been properly set and the punch head 21 can nowbe caused to descend so as to properly punch the first row on each ofthe four cards. The carriage 23 is now restored to its original positionand the cards are moved ahead to the extent of the distance between thetransverse rows thereon and the operation can then be repeated for theformation of the second row on each of the four cards.

Supposing that in reading a line of the design the first sixteen colorswill represent the sequence 1, 1, 3, 9, 8, 8, 8, 12, 14, 6,15, 3, 3, 3,11, 7 the keys t will be depressed in like sequence and the operationswill be as follows:

Calls yarn 3, color box 4, first position.Calls yarn 3, color box 4, second position. Calls yarn 11, color box 4,third position. Calls yarn 7, color box 4, fourth position.

The punching of the first row of each of the four cards is then effectedand all of the cards are advanced one step so as to bring the second rowin position to be punched, the carriage 23 is restored to its originalposition, and the above operations are repeated in connection with thesecond group of sixteen colors in the line, and so on, until the fullsixty rows of each of the four cards have been properly punched, thesefour cards then representing a complete line of knots from one edge ofthe fabric to the other. In the operation of the loom, therefore, card 1will efiect setting of the entireset of 240 color boxes and cause themto deliver the proper yarns for the first position, the second card willset all of the color boxes for delivering the proper yarns for thesecond position, and the third and fourth cards will properly set thecolor boxes for delivering the yarns for the third and fourth positions,respectively.

Instead of having four sets of lugs 33, one for each set of punch-jacks,the swinging blades may have but one set of such lugs as shown forinstance in Fig. 12, so as to act successively upon successive groups ofpunch-jacks of the same set, instead of upon like groups of successivesets, but in this case the carriage 23 will, between the successiveoperations of the keys 6, have to be moved as by the operation of anordinary space key, so as tocarry the set of lugs from one group to thenext of the same set, or from the last group of one set to the firstgroup of the next set, and the depression of the keys a will bedetermined not by the colors of the successive knots of the sets in arow across the web but by the color of every fifth knot of the set, thus:1, 5, 9, 13, 2, 6, 10, 14L,3,7,11,15,4,8,12,16.

Although the punching of the cards for use in a loom of the class towhich my invention relates is relatively complicated my improved machinecan be operated as easily as a typewriting machine and with no morecalculation on the part of the operator who has only to depress the keysin the sequence determined by the sequence of colors in a line of thedesign.

I have described each color box as operating in connection with a set ofwarp threads comprising four pairs but it will be evident that the setmay comprise a greater or lesser number of pairs than four, in whichcase the number of cards in the set will be correspondingly changed, andalthough I have described each color box as containing sixteen difierently colored yarns more or less than this number may be employed,depending upon the color requirements of the pattern to be produced.Reduction in the number of colors employed may also permit ofsimplification of the wedge mechanism and the use ofia lesser number ofwedges than four, in which case there may be a like reduction in thenumber of jacquard harness cords and of spaces on the card for eachcolor box of the loom and a similar reduction in the number of punchjacks of a group and of the swinging blades for actuating said jacks,and on the other hand increase in the number of colored yarns may leadto a corresponding increase in the number of wedges, harness cords, cardspaces, punch-jacks and operating blades therefor.

Instead of employing separately mounted keys connected to the key jacksby intervening mechanism the keys may, as shown in Fig. 13, be connecteddirectly to the key jacks, or if an operator is thoroughly familiar withthe character of the'punchings necessary to produce the difierent colorsthe punch jacks or punch locking bolts may be operated directly byhaind, in order to insure the desired setting of the punches in eachgroup prior to each punching operation.
